What you have appears to be a Rococo Revival piece from the 1860's, the finish is most likely a shellac over mahogany. The value may be in the 2 thousand dollar range, or was while the piece was in better shape. I'm not sure it would fetch 1 thousand in it's present condition. As for boiled linseed oil, that won't fix up the dirty finish. The best thing to do, as I see it would be, clean with lemon oil or naptha and polish with a cream polish, then satin wax and buff to a shine. The chipped or worn spots can be imporved with a colored wax stick after the cream polish. A good repair shop or qualified upholstery shop should go over all the joints with fresh hide glue and once the finish is in good shape the fabric can be replaced with a reproduction material that a good Interior Designer can show you. It is a great piece, the real deal was produced about 150 years earlier in the Rococo era but this is a very well made hand carved variation on the theme. Believe it or not the real deal was much more fantastic.
